Patentansprüche:Patent claims: ι . Verfahren zum Austreiben von Gasen aus Metallteilen elektrischer Entladungsgefäße, die Kathoden mit unselbständiger Entladung enthalten, durch Anlegen hoher Spannungen, dadurch gekennzeichnet, daß durch Einleiten hochgespannter Wechselströme eine Glimmentladung so lange erzeugt und die Metallmassen hierdurch so weit erhitzt werden, bis die an und in ■ihnen enthaltenen Gase frei werden.ι. Process for expelling gases from metal parts of electrical discharge vessels, which contain cathodes with dependent discharge, by applying high voltages, characterized in that by introducing high-voltage alternating currents, a glow discharge is generated for so long and the metal masses are thereby heated until the gases contained on and in them are released. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß zunächst bei verhältnismäßig geringem Vakuum die zu entgasende Metallmasse an den einen und eine andere Metallmasse oder sonstige Elektrode an den anderen Pol eines Induktoriums angelegt .und die Glimmentladung so lange aufrechterhalten, wird, bis etwa die Beschaffenheit des zu entgasenden Metalls 'erkennen läßt, daß die Gase ausgetrieben sind, und daß unmittelbar darauf das vollständige Auspumpen des Gefäßes auf die gewünschte endgültige Luftleere durchgeführt wird.2. The method according to claim 1, characterized in that initially at relatively low vacuum the metal mass to be degassed on one and another metal mass or other Electrode applied to the other pole of an inductor and the glow discharge so long is maintained, until about the nature of the to be degassed Metalls' shows that the gases have been expelled and that immediately then the vessel is completely pumped out to the desired final evacuation of air.
